Question 2

A patient presents with Tyndall effect after hyaluronic acid filler injection to the tear trough. What is the most appropriate treatment?

Accepted Answer

Hyaluronidase injection

Hyaluronidase dissolves hyaluronic acid filler and is the treatment of choice for Tyndall effect, which occurs when filler is placed too superficially.

Question 3

What is the primary mechanism of action of poly-L-lactic acid (PLLA) fillers such as Sculptra?

Accepted Answer

Stimulation of fibroblasts to produce new collagen

PLLA is a biostimulator that works by triggering a controlled inflammatory response leading to fibroblast activation and de novo collagen synthesis over several months.

Question 4

Which botulinum toxin serotype is used in all commercially available cosmetic neurotoxin products (Botox, Dysport, Xeomin, Jeuveau)?

Accepted Answer
